How many convention ballots will it take to elect a GOP nominee?

[TomC]

Three

[Sir Mohamed]

Two or three. The Trumpster won't reach 1,237 before the convention.

Delegate Binding

In similar fashion, a map of what ballot delegates become unbound after.

Green = 0 ballots
Red = 1 ballot
Blue = 2 ballots
Yellow = 3 ballots
Gray = Never, unless other conditions met.

How do the CA and NY primaries work?  Are they straight WTA, or are CD allocations involved?  I'm trying to get a better notion of what the delegate map will look like going into the convention.

CA is WTA by jurisdiction (i.e. the bulk are WTA by CD, with a small At-Large WTA pool).

NY is Winner-Take-Most by CD (winner 2, runner-up 1) with a 50% WTA trigger.  At large, it's proportional (20% threshold) with a 50% WTA trigger.  Due to that trigger, Trump should win the vast majority of delegates out of New York.

Depends on the following primaries:
Wisconsin
New York
California

[Stranger in a strange land]

I'm increasingly thinking that Cruz will win on the 2nd Ballot. Trump will get the most on the 1st Ballot, but still fall short of a majority.

Ohio's WTA, no release of delegates is the state party essentially saying: "Name the last time you won the White House without us.  Huh?  What?  Yeah, that's what we thought."
